Settlement analysis of the masonry umbrella vault of the Masegra Castle

• Abstract:

  In this work, the first results on the settlement analysis of the masonry umbrella vault located in the Masegra Castle (Sondrio, Italy) are presented. An umbrella vault is a particular type of cross vault in which the high number of sails is disposed according to an umbrella-shaped configuration. For geometry reasons, these vaults presents typically a good load-bearing capacity when subjected to vertical and horizontal loads. Therefore, the most critical issue is given by settlements of the supporting walls. A geometrical model based on NURBS surfaces has been derived starting from a detailed point cloud. A recently published method based on an adaptive kinematic limit analysis is adopted to find the cracks configuration deriving from a given base settlement.
